The SNAP-ODC-32-SRC-FM digital output module (load sourcing) provides 32 digital output channels in one compact SNAP module. This module is ideal for OEMs and others with applications with high point counts, or for those requiring a large number of digital output channels on one SNAP I/O rack. The high-density configuration reduces per-point costs of digital I/O systems by providing up to eight times as many I/O channels in the same space.

SNAP I/O high-density digital modules from Opto 22 provide 16 or 32 digital input or output points in one compact SNAP module. These modules are ideal for OEMs and others who have high point-count applications, or for anyone requiring more than 64 digital points on a single SNAP PAC rack. The high-density configuration reduces per-point costs of digital I/O systems by providing up to eight times as many I/O points in the same space.

SNAP high-density digital modules are part of the SNAP PAC System. They can also be used as part of intelligent remote I/O with an Allen-Bradley Logix PLC system.

This guide covers how to install and test SNAP 16-channel and 32-channel digital modules. These modules provide 16 or 32 points of digital input or digital output in the same space as a 4-channel digital module. They are ideal for OEMs and for anyone who needs up to 512 digital points on a single mounting rack.
